' PUMP-POWER.

SPECIFICATION forming part of Letters Patent No. 495,322, dated April11, 1893'.

Application filed December 12, 1892. Serial No. 454.953. (No model.)

To all whom it may concern-.-

Be it known that I, PETAR FRIOHETTE, a citizen of the United States,residing at Sheridan, Placer county, State of California, have inventedan Improvement in Pump-Powers and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to that class of intermediate devices designed toincrease the efficacy of a pump by increasing the number of its strokes,with the same movements of the initial driving mechanism.

My invention involves the principle of that mechanical movement in whichopposing racks are thrown alternately into and out of gear with anintervening pinion; and it consists in the novel construction,arrangement and combinations of parts hereinafter fully described andspecifically pointed out in the claims.

The object of my invention is to provide a device capable oftransmitting the full movement of the initial power device, whether itbe a windmill, horse-power or pump-handle, to operate the pump. Withthese powers, having vibrating or reciprocating motion, one half theirmovement, namely, the down stroke is lost as they operate the pump onlyon the up stroke. With my device the down stroke is' utilized as well asthe up stroke, and the pump is thereby operated faster and its efficacyincreased with the same amount of movement of the initial power.

Referring to the accompanying drawings for a more complete explanationof my invention,Figure l is a perspective view of my device. Fig. 2 isavertical section of same.

A is a frame, upon which is mounted the shaft B which, through the crankdisk 0, is adapted to drive the pump, unnecessary herein to show.

D is a vertically reciprocating rod, repre- F, upon the projecting endsof which are mounted and adapted to slide, the upper ends or heads 9 ofthe racks G. The lower ends of these racks play freely down through astirrup a on the bottom of plate a, and are guided therein by suitablylocated anti-friction rollers a Between these racks lies a pinion II,which, though it may be mounted upon the end of the drive shaft 13, ishere shown as mounted upon a short counter-shaft h, the other end ofwhich carries a gear h which meshes with a gear I) on shaft B, whereby,through proper proportions of these gears, the speed of rotation of thedrive shaft may be determined. The racks G, near their heads,

are connected by a link I to insure their 0p 1 eration in unison, andsaid racks are separated'by a distance greater than the diameter of thepinion H, whereby when one of the racks is in engagement with the pinionon one side, the other is entirely free of said pinion on' the otherside, and vice versa. The heads of the two racks are formed into or areprovided with inclined planes or cams represented by g, similarlyarranged and located, and adapted to impinge upon the fixed studs J,secured to plate a above, and preferably in the form of anti-frictionrollers. The efiect of this impingement is to throw both racks over toone side, here shown as to the right, when facing the machine, wherebythe left hand rack is thrown to engagement with pinion H and the righthand rack is thrown out of engagement therewith. In this movement theheads g of the racks slide freely upon the cross foot F.

Upon the racks, below their heads, here shown as upon one rack only (theright one), is a cam 9 This cam is adapted to impinge upon a fixed studK on plate a, and the effect is to throw both racks over in the otherdirection, that is to the left, whereby the right hand rack is thrown toengagement with the pinion Hand the left hand rack is thrown out ofengagement therewith.

Upon plate a, near each side of its middle port-ion, are the flanges L,which serve as guides, and with these flanges engage the hook fingers gsecured to the sides of the rack heads. In the plate a are made theslots 0. and a, the former being above the flange L and the latter belowit and removed from its vertical plane a little more than is the slot aUpon the head of one of the racks is a bracket M in which is mounted asafety lug m controlled by a spring m.

The operation of my device is as follows: When the rod D is at the limitof its up stroke, the studs J, by contact with the cams g of the rackheads, have forced the sliding heads of the racks and the racksthemselves over to the right, whereby the left hand rack is thrown toengagement with the pinion H and the right hand rack is thrown out ofengagement therewith. At this time the hook finger g of the right handrack lies above and outside of the vertical plane of the flange guide Lon that side, and the hook finger of the other rack lies inside of thevertical plane of the other flange guide. The safety lug m, under theinfluence of its spring m, is thrown into the upper guide slot a Now, asthe rod D descends, the left hand rack rotates the pinion H, and throughthe connections described the drive shaft 13 and crank disk 0 areoperated. The racks are first guided down true by the engagement of thesafety lug m with the slot a until the hook finger g of the right handrack passes to its engagement with the flange guide L on the outside andthe other hook finger passes down inside of its flange guide. Thus bothracks are held true by these flange guides during the entire descendingstroke. When the limit of the down stroke is nearly reached, and thehook fingers have cleared the flange guides below, the cam 9 coming incontact with the fixed stud K, throws both racks over to the left,whereby the right hand rack comes to engagement with pinion H and theleft hand one is thrown out of engagement therewith. Now, on the upstroke of rod D, the safety lug m engaging slot at first guides themovements of the racks, and then the hook fingers again engaging theirflange guides (this time the left hand one being outside and the righthand one inside), continue to hold said racks true. On this up movementthe right hand rack continues the rotation of pinion H in the samedirection. When the upper limit is reached the operation is repeated,theracks being thrown over, as first described. Thus it will be seenthat the drive shaft is operated on both movements of the rod D, and thepump is operated faster. The

safety lugm, as seen in Fig. 1,hasas'egmental shape, and is so affectedby its spring m that the bulging part only of its body will lightlyenter the slots a and a thus fully serving the purpose of a temporaryguide, until the hook fingers g engage the flanges L, at the same timepermitting said lug, under the action of its spring,to move forward intothe slots and to recede therefrom by simple contact of its ends inpassing over the slot ends.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Apump power consisting of adrive shaft to be connected with the pump,a pinion for operating said shaft, a reciprocating rod to be connectedwith the initial power, and having a cross foot, opposing racks one oneach side of the pinion and having heads mounted and adapted to slideupon the cross foot of the reciprocating rod, camson said racks, andfixed studs with which said cams engage whereby each of said racks arealternately thrown into and out of engagement with the pinion,substantially as herein described.

2. A pump power consisting of a drive shaft to be connected with thepump, a pinion for operating said shaft, a reciprocating rod to beconnected with the initial power and having a cross foot, opposing racksone on each side of the pinion and having heads mounted and adapted toslide upon the cross foot of the reciprocating rod, cams on said racksand fixed studs with which they engage for alternately throwing each ofsaid racks into and out of engagement with the pinion, hook fingers onsaid racks and fixed flange guides with which said fingers engage tohold the racks true in their movements substantially as hereindescribed.

3. A pump power consisting of a drive shaft to be connected with thepump, a pinion for operating said shaft, a reciprocating rod to beconnected with the initial power and having a cross foot, opposing racksone on each side of the pinion and having heads mounted and adapted toslide upon the cross foot of the reciprocating rod, cams on said racksand fixed studs with which they engage for alternately throwing each ofsaid racks into and out of engagement with the pinion, hook fingers onsaid racks and fixed flange guides with which said fingers engage tohold the racks true in their movements, and the safety lug and slots forguiding the hook fingers to their engagement with the flange guides,substantially as herein described.

In witness whereof I have hereunto set my hand.

PETAR FRIOHETTE.
